LVEA Sweep, Pre O3 start

Richard, Peter, Betsy

This morning at ~7:30 we asked Patrick to take the IFO out of Observing in order to complete the official hardware walkthru.  Since the checklist for the end stations from last week was already executed, we only performed the sweep in the LVEA.  Tomorrow is a maintenance window so we will be able to check ends once again at noon tomorrow (local time).  The checklist status from today: 

DONE - Make sure no one is in the LVEA

2 CRANES will be moved tomorrow - Cranes in their "parking spots" & their lights are OFF

DONE - Monitors/work stations are turned OFF (except VAC computers)

DONE - Phones unplugged (wall-wars & RJ11 plugs) & batteries pulled from handsets (Phone locations here)

DONE - Confirm no mechanical shorts onto HEPI.

DONE - Cleanrooms OFF • PSL in Science Mode

DONE - ISC Table fans OFF

DONE - Confirm wifi access points are unplugged (instructions)

DONE - Electronics racks (i.e. make sure no test equipment connected to a rack, unless work permit for it.)

DONE - Forklift NOT connected to charger

DONE - MAY BE a few still there, but not plugged into anything - Unplug unused power supplies/extension cords

DONE - Lights OFF (for end stations check lights via webcams)

DONE - Unplug power supplies for Valcom Paging System and 48V DC H1PSL Phone in Communications Room 163.

DONE - ALOG the LVEA has been swept.

 

Things out of nominal:

- SQZ IFR signal generator and associated hardware used to drive the SQZ AOM are used in the SQZ rack near HAM6 - these will be replaced/moved in a few weeks.

- Cranes will be moved to parking spot when out of lock during a maint period, then deenergized again.

- The HAM4 cleanroom curtains have sagged since the attempt to stow them last week, and are sitting on the SR3 OPLEV housing.  The cleanroom is off and this has been the state for many months (including PEM injections).  Since no one has complained that this is affecting H1, we will not try to fix them again.
